FFMPEG creates incorrect Source duration
13 septembre 2020, par Byron WhitlockWhen transcoding movies from an AVI to mp4 sometimes FFMPEG sets the "Source Duration" incorrectly.
This messes up playback on IOS devices. Specifically, it causes the video to cut out at "Source duration" while the audio still plays.
FFMPEG output transcode doesn't' show anything odd at all. Looks normal, no errors or warnings.
- Can I force FFMPEG to never add the "Source Duration" metadata?
- How do I edit the track metadata shown by mediainfo? I tried Mp4box, and a few others, but I can't seem to figure out how to edit track level metadata.
Thanks.
Log is below.

how to make omxh264enc output filler data ?
8 septembre 2020, par BlueWaterCrystalI require filler data from the encoder to artificially raise the bitrate to sustain constant bitrate.
normally x264enc does this but omx264enc doesn't seem to. even though there seems be a value within its code PROP_FILLER_DATA

x264 encoding severe quality loss
1er septembre 2020, par SolskGaerI used this repo to encode a mjpeg stream to a h264 one, but the output is not so good. The stream is a series of screenshot of an iPhone. In the output stream, even the lines between two items in the settings app are gone. How do I improve the output stream quality? Here is the code snippet that x264-go use to init an encoder

However, when I use the ffmpeg binary, the result was pretty good, so I guess I set wrong parameters, but I don't know which. Any suggestion would be appreciated. If you have better way to achieve this, I'll appreciate it.
For your information: I must do this using golang.

Playback of x264 encoded video in FLV is very slow (screen recording)
23 août 2020, par NewbieCoderTask:
I am recording the screen in 30 FPS and saving it to an FLV file. Images of the screen are obtained using the DXGI API in Windows. These images are then encoded into a video using libx264. Then the video data is stored in FLV container.Issue/Problem:
When the video is played in any video player, it is very slow. The frame rate information shows as 30 FPS but the playback feels like 15 FPS.Details:
Pseudo-code for the whole software:FPS = 30 target_time_for_each_frame = 1/FPS; timestamp = 0; while (true) { start_time = current_time(); image = capture_screen(); video_data = encode(image); writeToFLV(video_data, timestamp); timestamp += target_time_for_each_frame; end_time = current_time(); time_taken_for_current_frame = (end_time - start_time) // put the app to sleep to take screenshots only at 1/FPS or 33ms intervals. (delaying) if (time_taken_for_current_frame < target_time_for_each_frame) { sleep(target_time_for_each_frame - time_taken_for_current_frame) } }I am encoding with these parameters:
void init_encoder() { x264_param_default_preset(¶m, "veryfast", 0); param.i_width = 1920; param.i_height = 1080; param.i_fps_num = 30; param.i_fps_den = 1; param.i_timebase_num = param.i_fps_den; param.i_timebase_den = param.i_fps_num; param.rc.i_bitrate = 2500; param.i_bframe = 0; param.rc.i_rc_method = X264_RC_ABR; param.rc.f_rf_constant = 0; //param.rc.b_filler = true; param.rc.i_vbv_max_bitrate = param.rc.i_bitrate; param.rc.i_vbv_buffer_size = param.rc.i_bitrate; param.b_repeat_headers = 0; param.b_annexb = 1; x264_param_apply_profile(¶m, 0); }The timestamp given for the FLV file is correct:
timestamp += (1/30) // It is increased by 33 ms every loopI am setting pts of the input picture in this code:
int encodeYUV(uint8_t* data) { // convert BGRA to YUV using FFmpeg BGRA.data[0] = data; sws_scale(sws, BGRA.data, BGRA.linesize, 0, param.i_height, picIn.img.plane, picIn.img.i_stride); nal_size = x264_encoder_encode(h, &nals, &nal_count, &picIn, &picOut); picIn.i_pts += 1; // pts += 1 because timebase_num = 1, timebase_den = 30. So it increases by 33 ms return 0; }Increasing the pts to a very high value every loop (pts += 1000) makes the playback very pixelated and also plays very fast and repeats the same frame again and again sometimes.
Before this problem, I used tune as "zerolatency" and the playback was fine. But the video quality was not good so I had to remove it. And once I removed it, these problems came.
The parameters I'm using are not recommended for recording a video, but they are good for live streaming. My main purpose is a screen sharing app. I am using it as a screen recorder only to test if it works.
I am not sure if the problem is in the way I increase PTS or timestamp or if it is in the way I coded the delay in the app (to cap the FPS correctly). The problem really feels like it's related to only these factors (x264 PTS or FLV timestamp or delay code).
Any hints would be very much appreciated.
